Requirement Overview
Deliverables from this contract are to provide a service to undertake Hydrometric Monitoring for The Coal Authority, at coal and metal mine sites across the UK.
The Coal Authority intends to tender for the provision of Hydrometric Monitoring services. The framework will be divided into approximately 7 lots as detailed in this notice :
This is a non-exclusive framework agreement, and The Coal Authority is unable to guarantee the volume and value of allocated work.
Tenderers may submit a bid for single, multiple or all lot(s).
We may also split some of the lots regionally, so suppliers do not have to necessarily be able to cover the whole of the UK.
Lot 1 - Options Assessment
At locations where we don't currently have any existing flow monitoring, we will often conduct an options assessment.
This involves a site survey, options report and then detailed design drawings of the preferred option.
Suppliers will need to be able to demonstrate a comprehensive understanding of flow measurement techniques, measurement uncertainty, requirements of the relevant ISO standards, the pros and cons of each option and have demonstrable experience of designing and managing a contractor to install flow measurement solutions, often at remote sites. In some cases, the supplier who undertakes the options assessment will then be appointed to install the preferred solution.
Flow measurement solutions may include, but not be limited to: weirs and flumes, velocity meters, pipe flow meters, Stage-Discharge sites etc.
Lot 2 - Weirs and Flumes
This lot will involve the installation of weirs and flumes, either based upon design drawings from an options assessment (see Lot 1), to replace an existing weir or flume or to design and install within an existing channel.
Design and installation work should be undertaken in accordance with the relevant ISO standard, and all installation work will be carried out under CDM.
Lot 3 - Loggers, Water Level Sensors, Rain gauges and Water Quality Sensors
This lot will involve the installation of data loggers, water level sensors, rain gauges and water quality sensors.
Wherever possible, the data loggers should be installed on telemetry, and be battery powered without solar panels. We currently use Hydro-Logic Flexi-Loggers, OTT EcoLog and NetDL loggers, and our preference is to appoint suppliers who can install, maintain, calibrate and decommission these logger types. All installation work will be carried out under CDM.
Applications include:
- Water level sensors for flow monitoring at weirs and flumes - either pressure transmitters or non-contact sensors such as radar sensors.
- Groundwater monitoring in boreholes
- Rainfall monitoring
- Water Quality monitoring
Lot 4 - Velocity Meters
This lot will involve the installation, calibration, maintenance and decommissioning of velocity meters (either contact or non-contact).
Some of the installations will be in pipes requiring access to confined spaces, whilst others will be in open channels or pipes that are accessible from the surface.
The velocity meters should be compatible with either of the telemetry loggers listed under Lot 3, and in most cases will need to be battery powered, preferably without the need for solar panels.
All installation work will be carried out under CDM.
Lot 5 - Spot Flow Gauging and Water Quality sampling
This lot will involve spot flow gauging and water quality measurements, often taken at several locations within a particular catchment, or to validate existing flow measurement sites. Spot flow gauging techniques required will include Salt Dilution Gauging, Current Meter Gauging and ADCP Gauging, in accordance with the relevant ISO standard.
Water quality sampling will include taking samples for laboratory analysis (in most cases sent to SOCOTEC laboratories), and manual measurements using a hand held water quality meter.
Lot 6 - MCERTS
This lot will include MCERTS inspections at our Mine Water Treatment Schemes, flow meter calibration and QMS advice and auditing services.
Lot 7 - Hydrometric Monitoring (General Lot)
This will be a general lot, for projects which include aspects covered by more than 1 of the above.
Note: Any work involving construction or installation will be undertaken in accordance with CDM. Installation of loggers and velocity meters may be required on a hire basis from time to time.
